As a rough estimate, if UBZ gains 1.36 and K-O gains 1.22, then T-Hop/K-O with the ace-deuce count would win about 1.50 units per 100 rounds. T-Hop 1 Plus would do even better.

There is another more subtle difference between the systems other than PE and BC. UBZ 11 has an imbalance of roughly half of K-O. In other words, if UBZ 11 was a level one system, the imbalance per deck would be +2 instead of +4. The smaller number is better for small spreads in single deck(better playing efficiency) or for shoe games(better betting efficiency).
